PROX connecting rod kit for SUZUKI RM 125 from 2004 to 2011

PROX offers this connecting rod kit for SUZUKI RM 125 from 2004 to 2011. The rod passes the piston’s motion to the crankshaft. Its big-end bearing spins at very high revs and eventually develops play.

Why replace the connecting rod?

The benefits:

• Remove the play that causes noise and vibration.
• Make a high-hours engine reliable again.
• Cheaper than a complete crankshaft when the flywheels are good.

Why choose PROX?

ProX connecting rods are double-forged Japanese steel, heat-treated and shot-peened, made in Japan with the same shape and dimensions as the original part.

When should you replace the connecting rod on your SUZUKI RM 125?

Unusual vibration, a deep knock that follows engine speed or play in the con-rod: the bottom end needs a rebuild.

The manufacturer publishes no hour interval for this model: have the con-rod play checked at every piston change. Cross-Mania guideline: rebuild the bottom end every 2 to 3 top-end rebuilds.
